STEM-WINDING WATCH.

SPECIFICATION forming part of Letters Patent No. 238,464, dated March 1,1881.

Application filed December 11, 1880.

To all whom "it may concern Be it known that I, PHILLIP H. WHEELER, ofSpringfield, in the county oi Sangamon and State of Illinois, haveinvented a new and valuable Improvement in Stem-Winding Watches; and Ido hereby declare that the following is a full, clear, and exactdescription of the construction and operation of the same, referencebeinghad tothe annexed drawing, making a part of this specification, andto the letters and figures of reference marked thereon.

The figure of the drawing is a plan view of the mechanism.

This invention relates to the setting devices for stem-winding watches.

The invention consists in the construction hereinafter described, andparticularly pointed out in the claim.

Inthe drawing hereto annexed, A is the pillar'plate.

B is the yoke, pivoted at a, and carrying the bevel -wheel 0. Throughthis the pendant winds and sets the watch.

Upon end D of yoke B is journaled the bevel-wheel D, through which wheel0 winds the watch. The other end, E, ofsaid yoke carries anotherbevel-wheel, E, journaled at c to mesh with wheel 0. This end extendsbeyond said wheel E into a recess, f, of the pillarplate A. Thisextension is beveled off at e, and has the corner cut off at g.

G is a pawl pivoted near the bevel e, and when loose its end h is forcedby a spring, H, against such bevel.

I is a finger-bar pivoted at it, and when shoved inward, having its end70 hearing against the end E of the yoke and a thumbpiece, I, projectingthrough opening a in the (Model.)

watch. \Vhen this finger-bar is shoved in it presses pawl G from off endE, releasing the yoke B, and permitting spring N to hold the wheel. Dinto engagement with awheel within for winding the watch. Whenfinger-bar I is withdrawn spring H throws pawl G around, and its pointh, riding up bevel c. forces the end E of the yoke B in, releases wheelI) from engagement, and rests upon the cut-off corner g. This actionthrows bevel-wheel E into engagement with the minute-wheel, when, byoperating the pendant, the hands can be turned in either direction andthe watch set.

It will be noticed that when the finger-bar I is shoved in and pushesthe pawl Gr away said pawl bears, by its end,p, against the fin- &

ger-bar, and by its friction prevents the accidental displacement of thesame.

A swing-yoke in a stem-winding and handsetting watch has heretofore beenheld and released by a pivoted lever, and I claim protection only forthe peculiar construction herein shown, described, and specificallyclaimed.

What I claim is- In a stem-winding watch, the combination, with the yokeB, having one extension carrying a wheel, D, and an opposite extensionbeveled at its end at c, and cut away at g. carrying a bevel-wheel, E,of the springs H and N, pivoted pawl G, and pivoted fingerpiece I,substantially as and for the purposes set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

PHILLIP H. WHEELER.
